16 Claims.

This invention relates toimprovements in devices for liquid containerswhich are adapted to prevent tampering with the contents thereof and hasfor its principal object to provide a simple, inexpensive and practicaldevice of the indicated character which will only permit the removal ofthe liquid contents of the container with which it is associated andwhich will apprise the consumer when an attempt has been made toadulterate the contents of the container or substitute a spuriousproduct.

Other objects well as thenovel details of the construction of a deviceembodying the invention will become apparent after consideration of thedescription herein below set forth taken in conjunction with theaccompanying drawings in which similar reference characters identifysimilar parts in the several views and in which Fig. 1 is a frontelevation of the top portion of a bottle provided with a device made inaccordance with the invention; Fig. 2 is a central vertical sectiontaken at right angles to Fig. 1; Fig. 3 is a rear elevation of Fig. 1partly in section; Fig. 4 is a top plan view of the bottle closure; Fig.5 is a section taken along the line 5-5 of Fig. 2; Fig. 6 is anelevation showing the valve elements which control the removal of theliquid from the container; Fig. 7 is an elevation partly in sectionshowing the casing for the valve elements illustrated in Fig. 6; Fig. 8is a top plan view of the casing shown in Fig. '7; Fig. 9 is anelevation partly in section showing the means for extracting the liquidfrom a bottle provided with my novel device; Fig. 10 is a centralvertical section of the top portion of a bottle fitted with a modifiedform of the invention; Fig. 11 is a top plan view of the closure shownin Fig. 10; Fig. 12 is a section taken along the line l2--I2 of Fig. 10;Fig. 13 is a top plan view of an element of the device shown in Fig. 10;Fig. 14 is an elevation of anotheriorm of the invention showing it inposition for insertion into a closure sealed in the neck portion of abottle, the latter being shown in vertical section; Fig. 15 is a topplan view of the mouth of the bottle shown in Fig. 14; Fig. 16 is avertical section of the parts shown in Fig. 14 after the device has beeninserted into the mouth of the bottle; Fig. 17 is a top plan view of thedevice shown in Fig. 16 and Fig. 18 is a section taken along the linel8|8 of Fig. 16.

Referring more particularly to Figs. 1 to 8 of the drawings, thereference character l designates the neck of a bottle which is providedat its top portion with an external screw thread 2. A closure cap 3having an internal screw thread t is screwed on the thread 2 provided onthe bottle neck. The closure cap maybe made of any suitable material andwhen made of a brittle substance such as phenol plastic material may beformed with a discharge aperture 5, as shown in the 5 drawings whichwhen not in use may be closed by a small cork 6. Positioned within themouth of the bottle is a hollow cylindrically shaped casing I made ofnon-corrosive material and provided at its upper end with an outwardlyextending flange 8 adapted to seat on the top edge of the neck of thebottle and support the casing within the mouth of the bottle. Acylindrically shaped cork 9 is provided on the exterior surface of thecasing l adjacently to the flange 8 to assure a tight fit between thecasing and the inner surface of the neck of the bottle and to preventleakage at this point. An annularly shaped washer it made of anysuitable material is provided between the flange B and the closure 3 toseal the connection between these parts. It will be seen that with theabove described arrangement the liquid contents of the bottle will beprevented from leaking out between the casing I and the inner surface ofthe bottle neck or the casing and the closure cap 3 either duringshipment or handling of the bottle or when the contents thereof arebeing sold to the consumer as will be hereinafter more fully explained.The lower end of the casing I is provided with an inwardly extendingflange 30 H upon the upper side of which is mounted an annularly shapedwasher l2 which may be made of cork, rubber or any other suitablematerial and which has an outside diameter substantially the same as theinside diameter of the casing so that 35 it fits snugly in the casing.Seated upon the washer I2 is a disc-shaped valve element it adaptedunder normal conditions to close the passageway formed by the innerwalls of the washer l2 and the flange l l and having an outside diameterslightly less than the interior diameter of the casing i so that when itis in opened position the fluid contents of the bottle may pass betweenthe outer edge thereof and the interior surface of the casing. Avertically disposed spring it which is secured to a reduced portion B5of the valve element It maintains the valve element in closed positionwhen the liquid contents of the bottle are not being withdrawn. Theupper end of thespring It is secured to the reduced portion it of anupper disc-shaped valve element it which is retained in the casing l bymeans or the inwardly projecting stops it provided on the inner surfaceof the casing adjacent its upper edge. The spring it is of such size andstre that in its compressed condition between the valve elements I: andI1, it exerts sufllcient pres sure on the valve element I3 to maintainthe I latter seated on the washer I2 even when the bottle is tilted to apouring position. In accordand permit the liquid contents of the bottleto flow past such element and into the casing. The discshaped valveelement H has a diameter substantially the same as the valve member I3so that any liquid flowing into the casing from the bottle will passbetween the outer edge of such member and the interior surface of thecasing I. The

. thickness of the valve element I'I, however, may

be approximately twice that of the valve element I3 and the valveelement I1 is provided with vertically disposed channels or grooves 20on its outer edge which enable a greater flow of the liquid past suchelement and which enables it to be readily inserted into or removed fromthe casing past the stops I8. The valve elements I3 and I1 may be madeof any suitable material such as non-corrosive metal, phenol plasticmaterial, glass, porcelain or cork.

It will be seen from the above that when the said parts are in positionin the mouth portion of the bottle, the lower valve member I3 in thecasing 7 is seated tightly on the washer I2 under the compression of thespring I4 thereby preventing any liquid in the bottle from flowing outthrough the passageway formed by the inner walls of the washer I2 andthe inwardly extending flange I I at the lower end of the casing I. Asthe tension of the spring I 4 on the lower valve member I3 issuificiently great so that said element cannot be displaced by theweight of the liquid or by shaking the bottle in inverted position itwill be seen that the liquid contents of the bottle are sealed thereinand cannot be taken out until the bottle is placed in a suitable devicefor the removal of the liquid contents thereof as will hereinafter bemore fully explained. Furthermore, no liquid can be inserted in thebottle as any attempt to force liquid into the bottle will only resultin seating the valve element more tightly on the washer I2.

The bottle closure 3 is provided with an arcuately shaped projectingportion 2| having a slot or opening 22 through which extends the innerportions of a destructible sea1'23. The two depending portions of theseal 23 extend down below a relatively deep annular groove 24 formed onthe neck of the bottle between the annular bead 25 and 26. Thedestructible seal may be made of cellulose, metal foil, fabric or anyother suitable material such as is ordinarily used for this purpose andmay be weakened by a scoring provided at the point where it is folded onthe arcuately shaped portion 2|. Seated in the groove 24 and encirclingthe depending portions of the seal 23 is a substantially heavy,indestructible and non-removable band 21. The outer de pending portionof the destructible seal 23 may be provided with a pair of parallel cutsextending lengthwise of the seal and through which the metal band 21passes so that a part of said outer portion of the seal is positionedoutside of the band, as shown in Figs. 1 and 2. The diameter of theinner side of the band should be approximately the same as the diameterof the inner wall of the groove 24 so that it tightly wedges the twodepending portions of the destructible seal 23 against the inner wall ofthe groove thereby permanently maintaining those portions of thedcstructible seal in place on the bottle and preventing anyone frommounting a new destructible seal on the bottle. The band 21 isconstituted of metallic material and has such rigidity of constitutionand form that on application of prying pressure applied between the wallof the bottle and the inner periphery of the band, the band willmaintain its shape and position until the bottle is so deformed ordestroyed as a result of the prying pressure as to be incapable offurther use. While the band may be made in one piece, I prefer to makeit of two pieces, one end of each piece being welded together in amanner well known in the art when the parts thereof have been mounted inthe groove. As shown in Figs. 2 and 3 of the drawings, the continuity ofthe groove 24 about the neck of the bottle is broken by a partition ofglass 28 which extends transversely across the groove from the lowerhead 26 to a point substantially midway of the groove and is integrallyformed with the lower bead 26 and the inner wall of the groove. The twoends of the arcuately shaped pieces of the band 21 which are joinedtogether at this portion of the groove intermediate the partition 28andthe upper wall of the groove, as is clearly shown in Fig. 3, arereduced in cross-section so that such end portions of the band cooperatewith said partition to prevent any rotational movement of the band onthe bottle. It is to be understood that other partitions or stops may bepositioned in the groove, as may be found necessary.

It will be seen that the above arrangement provides the bottle with adouble seal which will prevent anyone removing the closure 3 of thebottle and tampering with the contents thereof since it is exceedinglydifficult and practically impossible to remove the permanent seal orring 21 and place a new destructible seal 23 on the bottle and thatportion of the destructible seal which is permanently maintained in theexternal groove 24 by the band 21 will serve as notice to the customerthat the bottle originally was provided with a destructible seal andthat the contents of the bottle has been tampered with.

The consumer, however, may readily open the bottle by destroying thedestructible seal 23 and unr' screwing the closure 3. With the closureremoved, the consumer is then enabled to withdraw the casing 'I togetherwith the elements contained therein and to pour out the liquid contentsof the bottle in the ordinary manner.

When the contents of the bottle, however, are to be sold in smallquantities to a consumer as in the case where liquor is to be servedover the bar, the seal 23 is left untouched and the cork 6 is removedfrom the opening 5 in the top of the closure 3. The bottle is thenplaced in inverted position on a dispensing device such as isillustrated in Fig. 9. As shown in the indicated figure, the dispensingdevice may comprise a supporting base 30 which may be secured to asupport by means of screws 3I. Intermediate the upper and lower ends ofthe base is secured thereto a bracket 32 provided at its outer end witha substantially annular shaped support comprising an upper annularportion 33 and a lower annular portion 34 of smaller diameter andintegral therewith. The lower portion 34 is adapted to support thecylindrically shaped neck portion of a flask shaped casing 35 which isprovided at its lower end with an externally threaded annularly shapedconnection 36. The casing 35 may be made of ,glass,,metal or any othersuitable material. Positioned within the upper annular portion 33 is aplug or closure 31 made of compressible material such as soft rubber andhaving a reduced portion which extends into the neck portion of thecasing 35.. The plug 31 is provided on its upper end with an annularrecess 38 adapted to receive snugly the closure 3 of the bottle. Thebottle is supported in inverted position on the plug 31 by means of apair of horizontally disposed-spring arms 39 which are fixedly securedat their inner ends to the base so. Extending axially of the plug 31 isa vertically disposed pipe 40 which communicates at its upper end withthe recess 38 and forms a direct connection between the opening 5 in theclosure 3 of the bottle and the interiorof the casing 35. The lower endof the pipe is positioned close above a rigidly formed outlet 4!,supported centrally of. a rubber diaphragm 42 and extendingtherethrough. The diaphragm 42 is integrally formed with an annularlyshaped coupling member 42 adapted to screw on the threaded connection 35at the lower end of the casing 35. Positioned beneath the diaphragm 42is a measuring cup 43 which is supported by apparatus adapted to keepthe mouth portion of the measuring cup in tight engage ment with theunderside of the diaphragm 42. The apparatus for accomplishing this maycomprise a bracket 44 secured at its inner end to the supporting base 30and provided at its outer end with an opening through which extends arod 55 havingat its upper end a cup holder 55 for supporting themeasuring cup and at its lower end a handle 4'l adapted to be grasped bythe dispenser. A spring 48 which is positioned between the cup holder 46and the bracket M and encircles the rod 45, maintains the former inupward position so that the measuring cup is held tightly against thediaphragm 52. The cylindrically shaped neck portion of the casing 35 isprovided with an opening 415 which is in alignment with an open end of apipe 50 integrally associated with the lower cylindrically shapedportion 34 of the bracket 32, the other end of said pipe being connectedto some means (not shown) for supplying a vacuum in the casing 35, suchas a pump or a suction device operated by water. It will thus be seenthat when the bottle is mounted in inverted position on the plug 3'5, asabove described and shown in Fig. 9, so that the opening 5 in theclosure 3 is in alignment with the opening in the upper end of the pipeMi supported by said plug and a vacuum created in the casing 35 throughthe pipe 50, the vacuum will cause the valve element l3 in the casing '1contained in the bottle to be drawn downwardly into opened position, asviewed in Fig. 9 and cause the liquid contents of the bottle to be drawnthrough the openings in the flange H and washer l2, through the spacebetween the valve element l3 and the inner side of the casing and intothe casing i. The liquid passes from the casing '6 through the spacebetween the valve element H and the inner side of the casing 5, throughthe opening 5 in the closure 3, down through the pipe 45 in the casing35 which discharges the liquid through the outlet 4| into the measuringcup 45. When the measuring cup has been filled to the desired height,atmospheric conditions are restored in the casing 35 thereby stoppingthe flow of liquid from the bottle. The dispenser then pulls the handle41 downwardly against the tension of spring 48 thereby enabling him toremove the cup from the device. A customer buying a drink from a bottleprovided with a device of the invention is assured that he is gettingthe genuine article as he knows that the valve arrangement within thebottle prevents anyone from putting a spurious liquid in the bottle andthe double seal 23, 21 which is in prominent position on the bottle willnotify him when the bottle has been tampered with.

In the modified form of the invention shown in Figs. 10 to 13, thewasher i2, the valve elements l3? and i1 and the spring H are containedwithin a. hollow cork casing 5| suitably secured to a closure 52, thecombined casing 5i and closure 52 having the outward appearance of anordinary cork closure. In this case the casing 5i has an externaldiameter substantially the same as the inside diameter of the neck ofthebottle so that it snugly engages with the inner wall of the latterand performs the functions of an ordinary cork. The bottom wall 53 ofthe casing 5| is substantially thicker than the side walls thereof sothat a suitable support is formed for the valve elements. Dueto the factthat the closure 52 itself confines the elements within the casing it isunnecessary to provide stops such as the stops it in the preferred formof the invention. As the top surface of the upper valve element ll seatsagainst the under surface of the closure 52 because of this arrangement,it is necessary that the top surface of such element be provided withgrooves or channels, such as the transversely disposed grooves 54illustrated in Fig. 13 which communicate with the vertically disposedgrooves 20' provided on the side surfaces of such element in order thatthe liquid drawn into the casing Si by the dispensing device will beenabled to flow out through the opening 5' provided in the closure 52.The destructible seal 55 in this form of the invention may extend acrossthe top of the closure 52 so that the depending portions thereof arepositioned on opposite sides of the bottle neck, such depending portionsextending down below the annular groove 56 formed in the neck of thebottle and partly positioned therein under the substantially heavy,indestructible and non-removable metal band 51.. The upper annular bead58 on the neck of the bottle and the outer edge portions of the closure52 are preferably recessed so that the depending portions of the seal 55can lie against the outer surface of the neck of the bottle and so thatthe seal is prevented from slipping ofi the bottle. A perforation 59 isprovided on that portion of the seal 55 which extends across the closure52 so that the cork 5' may project therethrough.

The cooperating elements in the device of my invention instead of beingwholly assembled on the bottle at the filling establishment as shown inFigs. 1 to 13, may be in part assembled on the bottle when the latter isfilled and in part assembled on the bottle at the place where thecontents thereof are to be sold in small quantitles to the consumer. Inaccordance with this form of my invention, instead of assembling thevalve elements in the bottle at the filling establishment the bottle isclosed by a cylindrically shaped cork 55 which is adapted to be insertedin the bottle so that the upper edge thereof lies flush with the top ofthe bottleas shown in'Fig.

14. A cap 65 adapted to threadedly engage with the screw threadsprovided on the mouth portion of the bottle is then screwed intoposition on the latter. The cap 56 is provided with a centrally disposedopening Bl which exposes the an annular recess within which is secured adisc 13 having a diameter'substantially the same as the opening 61 inthe cap 66 and constituted of sufllciently strong material to preventtampering with the liquid contents of'the bottle through the opening inthe cap 66. Integrally formed with the lower edge of the cap is anoutwardly projecting extension 68 provided with an elongated opening 69through which extends the inner portion of the destructible seal I0, thetwo depending portions of said seal being sealed in the external grooveH on the neck of the bottle by the permanent seal 12 as hereinbeforeexplained. The bottle which is sealed in the manner above described issold in this condition to the trade.

The device of my invention which controls the removal and insertion offluid in the bottle is sold separately to the trade in combination witha cork-removing device which, when once in-- sorted into the bottle, canonly be removed therefrom by smashing the bottle. As shown in Figs. '4and 16 this combined arrangement comprises a casing 14 provided at itsupper end with a discharge nozzle 15 and at its lower end with anoutwardly extending flange 16 which seats on the upper surface of anoutwardly extending flange TI provided on the upper end of a verticallydisposed tubular member 18. The outer edge portion of the flange ll isturned over the flange 16 of the casing 14 so that said casing issecurely held in position on the flange l'l. Positioned within thecasing 14 and seated on the flange I1 is an annular washer 19, theopening of which is normally closed by the lower valve element 80 undertension of the vertically disposed spring 8| which is secured at itsupper end to the upper valve elezrent 82. The organization of the partswithin the casing 14 is similar to that already described in thepreferred embodiment of my invention. Secured within the lower endportion of the tubular member 18 is a hollow cylindrically shaped member83 hav ng two depending arms 84 which are vertically disp sed in spacedparallel relation, the distance between such arms being substantiallygreater than the diameter of the tubular member 18. The depending arms84 are each provided at their lower ends with a downwardly extendingreduced portion 85 which termnates in a point. The arms 84 are also eachprovided with a longitudinally extending opening or slot 86 throughwhich a V-shapcd spring tensioned member 81 is adapted to move. Each ofthe members 81 is mounted on an arm 84 so that the apex thereof isnormally positioned outwardly from the arm supporting it, the lower endof said member being supported on a pin 88 rotatably mounted on bearingsprovided at the lower end portion of tl-e slot in said arm and the upperend of said member being provided with an upwardly extending portion 89adapted to engage with the inner side of said arm and limit the outwardmovement of the member 81. A spring 90 which is suitably connected tosaid member 81 and said arm 84 normally tends to keep the member inoutward position and yieldingly resists inward movement of the same. I

It will be seen that when the port'cns 85 of the arrangement abovedescribed, are in erted in the cork and downward pressure is applied,the shoulders formed by the portions 85 and the lower end portions ofthe arms 84 engage with aoeaaac the upper surface of the cork and forcethe latter downwardly into the bottle.. During the passage of the arms8| through-the neck of the bottle, the spring-tensioned members 81 areforced into retracted position against the tension of the springs 90 bythe inner surface of the neck portion of the bottle. When the members 81have passed the neck of the bottle, however, they are moved outwardly bythe springs 90 and abut against the inner surface of the shoulder of thebottle as shown in Fig. 16, thereby preventing the removal of the devicefrom the bottle. The tubular member 18 is provided with an annularlyshaped cork 92 for tightly sealing the device in the neck of the bottleand which in its passage into the bottle turns the inner edge portion ofthe bottle cover downwardly around the top of the bottle as shown inFig. 16. It will thus be seen that when the device is inserted in thebottle, the arrangement is fundamentally the same as that shown in thepreferred form of the invention and the liquid contents of the bottlecan be dispensed in small quantities by means of the apparatus shown inFig. 9 in the manner above described. The portion 85 of the arms 84 holdthe cork securely within the interior of the bottle so that it cannotinterfere with this operation. In order to remove this arrangement fromthe bottle for use on another bottle, it is necessary that the bottle besmashed as the spring-tensioned members 81 will not permit the removaltherefrom through the neck of the bottle.

While I have shown and described the casing 1 in the preferred form ofthe invention as being supported on the mouth portion of the bottle, itis obvious that it may be permanently or removably secured to the bottleclosure 3 in any suitable manner such as by cement, or by turning theouter edge portion of the flange upwardly and inserting it into a recessprovided in the closure 3 or by providing such upturned portion with ascrew thread which is adapted to be threadedly received by the closure3. The valve elements comprising the inner seal of my vacuumnon-refillable closure may have other forms than that illustrated andmay be so associated with the coiled spring that the inner seal operatesonly under a predetermined degree. of

vacuum. The lower valve element 13 may be externally threaded andadapted to loosely screw into screw threads provided in the inletopening in the lower end of the casing 1. In this case the coiled springmay be eliminated and the upper valve element made suificiently heavy sothat it maintains the lower valve element closed when the contents arenot being removed from the bottle. When the bottle is placed in invertedposition on a suitable vacuum device, however, the upper element willfall away from the lower valve element and the contents thereof can bedrawn out through the passage formed by the screw threads on the elementI 3 and the inlet opening of the casing. Means may be associated withthe lower valve element l3 to enable the weight of the liquid to assistin moving such element to opened position. The upper element l1, insteadof being movably positioned in the casing, may be made of cork or rubberand fitted tightly into the casing. In this case the element may begrooved as shown in Fig. 13 or passages may be provided through theelement. The opening in the bottle closure may be omitted, in which casea hole is punched in the closure just Drlbr to placing it on thedispensing device. The

hole in theclosure whether formed in the closure or produced after thebottle is sealed need be no more than a minute opening thereby making itimpossible to tamper with the parts comprising the inner seal throughsuch opening.

The opening in by other means closure fitted over the bottle than acork,

the bottle closure.

closure may be closed such as a rubber In the modified form of theinvention shown in Figs? 14: to 18, the 1:)

closing the bottle but solid closure instead. In this case, the devicefor controlling the ottle need not have a cork for may be provided witha liquid is in addition provided adjacently tothe reduced pointedportions 85 with a round cutter which comes into contact with theclosure after the said pointedportions or prongs have been forced intothe closure.

The invention is also susceptible to other changes in the constructionand arrangement of the parts without the appended claims and may bedeparting from the scope of used to equal advantage on containers madeof a material other than glass.

The invention is of particular value for bottles or containers filledwith wines, liquors, bever-' ages, toilet products and pharmaceuticalproducts as it maintains the original mellowness, odor or strength ofsuch liquids until they are used.
